GYRATORY CRUSHER.

SPECIFICATION forming part of Letters Patent No. 575,015, dated January 12, 1897.

Application filed September 9, 1896. Serial No. 605,321. (No model.)

To aZZ whom, it may concern: the head are projected a number of soft-iron Be it known that we, KLAS H. TERNSTEDT staves H, as clearly shown in Fig. 6 of the and JOSEPH H.TEMPLIN,citizens of the United drawings, each of these staves consisting of States, and residents of Birdsborough, in the two pieces cast into the head and allowed 5 county of Berks and State of Pennsylvania, longitudinal motion as the head shrinks in have invented certain new and useful Imcooling, this construction being found in provements in Gyratory Crushers, of which practice to give a stronger head than conthe following is a specification. tinuous staves.

Our invention relates to improvements in The two pieces forming one stave are set 10 gyratory crushers; and the object of the in the core, so that when the head is cooled invention is to suspend the head freely and and shrunk they abut against each other and independently of the shaft, as set forth in an form, practically, one stave, with bearing on application filed byKlas I-I.

Into the opening in pering from the bottom up on angles correspending to the set angle of the head and the lower side of the flange faced off at right angles to this. By these means we insure a full-length vertical bearing on a bushing I) and a horizontal bearing on c in the same plane. Bushing l) is inserted, so that in case of wear it can be taken out and replaced and the head and sleeve kept in their proper position. c is beveled off on the edges, so as to throw any dust cnterin g the chamber into the annular groove surrounding it,and from there it can be cleaned out.

The inside of the sleeve E is bored out to loosely receive the upper end of the shaft F. At its lower end it is beveled off to receive a suitable packing EZwhieh is held in place by ring E The function of this packing is to keep dust from getting between the shaft and sleeve E, which would cause wear. The top of this sleeve is covered by a conical cap E, which serves to keep out dust from above and at the same time provides a convenient means for oiling both inside and outside of the sleeve E.

E is an eyebolt which when removed the inside of the sleeve may be oiled through the hole E in the top of the conical cap E and the outside by simply letting the oil run over the face of the conical cap E.

G designates chills provided with beads G on the outside, both at the top and bot-tom. These beads fit into grooves G formed in the hopper l3, and by having them so located the strain is lessened and liability to tear off in case of lifting or tilting of the chillsis avoided.

F designates the driving-bushing, which snugly fits into a projection in the base A, and which is bored out ecceutrically on the line of the head to receive the lower end of the shaft F, the sleeve or bearing for the shaft being bored out slightly flaring from bottom to top to give a clearance to the shaft and form a receptacle for oil and is extended beyond the top face of the bushing and beveled off, as shown in Fig. 3 of the drawings. On this beveled portion is located a ring a, conforming in shape with f, but fitting the shaft snugly. The upper portion is cup-shaped to form a reservoir for oil and waste, which forms the dust'protector for the shaft-bearing. Oil-grooves d are cut in the face bearing against the shaft and its top is covered with a plate fitting the shaft loosely, and into this cover is inserted an oil-cup d. This design enables the operator to hold the co veringplate and oil-cup stationary while the machine is running and fill the cup with oil.

The d riving'bushin g F", to which the bevelgear N is secured, is smaller-in diameter than the part in the bearin g. Thereby a shoulder a is formed for the gear to rest on. The gear is held by a hook-key or keeper a, which can be easily withdrawn when the bushing is to be taken out for rebabbitting. By having a straight face 011 the bushing it can be dropped down through its bearing, leaving the gear central and intact and ready to slip over the bushing when the same is replaced. Into an enlargement in the lower part of the shaftbearing is loosely inserted the protracted portion of j, which forms the support for the shaft F. The friction is minimized by the use of the hardened-steel disks 9 g.

The radius of the main body of f is a little less than the distance from the center of shaft F to the nearest point on the outside face of the bushing. Thus a shoulder is obtained on which rests the bushing itself, and at the same time contact between 1" and the bottom plate 0 is avoided under all circumstances. f is supported ecccntrically on the center line of the bushing F itself by hardened antifriction steel disks, the whole submerged in a bath of oil. The bottolnplate O ishingcd to the downwardly-projecting part A of the base-plate A, which forms the bcarin g for f, and is secured to it by means of bolts and nuts.

0 designates a hand-bar used to lessen the weight of the bottom plate 0 on the operator when dropping it.

s s designate oil-wells communicating with each other through the channels 5, and also with the bearing for F through suitable oilholes. These wells and comiccting-channel are covered by a plate and communicate by means of the pipe S with the cup S, which is placed either outside or inside of the base A. The bottom of these oil-wells have means fordrawing oif sediment and oil, as at 3 and also an overflow-pipe s.

M designates a bevel-pinion which meshes with gear N, and is secured to the drivingshaft K, which is carried on rollers R in bearing P, which is secured to the overhanging part A of the base A.

To the outer end of the driving-shaft K is secured the sleeve L, which is flanged, as shown in the drawings, and has radial annular pockets therein disposed at proper points. On the body of this sleeve L is secured the hub of the combined driving-pulley and flywheel K.

7: designates an annular ring formed on the combined driving-pulley and lly-wheel K and projecting over the flange or sleeve L. This ring is provided with holes 7& corresponding in size and in alinement with the pockets in the flange or sleeve L, and through them are inserted the brake-pins h and h. To keep these brake-pins in their places against the action of the centrifugal force, a band L is used, which is clearly shown in Fig. 5 of the drawings, which encompasses the annular ring 7t, and is held in place by a pin 7;, entered in an L-shaped slotin the band.

Then the pins break and have to be re placed, it is only necessary to disengage the band L from the pin 7.; and push it back toward the arms of the fly-wheel. By having the bottom bearing for the shaft F and bushing F arranged as shown the base A can be cast in one piece with the body A, and only the small bottom plate 0 has to be swung to one side when the bushing is withdrawn for repairs.

T designates an opening formed in the base A at a point Where the bearing P is entered. This opening is formed large enough to allow the gear-wheel N to pass in and out of the same, and said opening is closed or opened by means of a sectional door it, as shown clearlyin Figs. 2 and 7 of the drawings, the central part of the door being made large enough to allow of the insertion and withdrawal of the pinion. Either side door can then be opened and the running-gear inspected and oiled through the same.

The advantage of hinging the wings or sections of the door to the central or main sect-ion is such that it enables the operator to have access within the casing from each side of the machine from the point where the operator may be standing, instead of his having to pass all of the way around the machine for the purpose of entering the casing, as would be the case if the door was made of the ordinary construction, which would occasion loss of time and inconvenience in removing bodily the door of the casing.
